Coordination of the heat drawn off in
the secondary circuit when the heat
pump produces an excess of heat or
the heat drawn by the secondary cir-
cuit is suddenly choked off.
Settings:
0 No heat drawn off
1 Heat will be drawn off only in case
of a critical excess, i.e. if critical
temperatures were reached in the
heat pump circuit or the minimum
heat pump runtime has not yet
been reached.
2 Heat will be drawn off, even if the
excess heat being created is not
critical for the heat pump

When DHW priority has been
enabled, the DHW cylinder will be
heated, until the selected DHW tem-
perature (see operating instructions
Vitocal 300) has been reached or the
period selected under "
max. DHW
runtime
" (see page 99) has expired.
Only then will the heating circuit be
supplied with heat.
